|
|||
|
|
|
|||
|
|

|
|||
|
|
```python
|
|||
|
|
def validate_fasta(file_path):
|
|||
|
|
checks = {
|
|||
|
|
"header_format": r"^>[\w\|]+",
|
|||
|
|
"sequence_chars": r"^[ACGTURYKMSWBDHVN\-]+$",
|
|||
|
|
"no_empty_sequences": True,
|
|||
|
|
"unique_ids": True
|
|||
|
|
}
|
|||
|
|
return run_checks(file_path, checks)
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
**Newick格式检查**：

|
|
data = json.load(open(file_path))
|
|||
|
|
return {"valid": True, "keys": list(data.keys())}
|
|||
|
|
except json.JSONDecodeError as e:

|
|||
|
|
|
|||
|
|
**序列质量检查**：

|
|||
|
|
|-----|---------|---------|---------|
|
|||
|

| 序列长度 | 100-5000 | <100或>5000 | <50或>10000 |
|
|||
|
|
| GC含量 | 30-70% | <20%或>80% | <10%或>90% |
|
|||
|
|
| N比例 | <1% | 1-5% | >5% |

|
|
|

|
|
**统计合理性检查**：

|
|
- 基因数量是否符合预期（参考近缘物种）
|
|||
|
|
- 序列长度分布是否合理
|
|||
|
|
- 染色体分布是否均匀
|
|||
|
|

|
|||
|
|
|
|||

|||
|
|
|
|||
|
|
### 4. 一致性验证 (Consistency)
|
|||
|
|
|
|||
|
|
**阶段间一致性**：
|
|||
|
|
```python
|
|||
|
|
def check_stage_consistency(results):
|
|||
|
|
issues = []
|
|||
|
|
|
|||
|
|
# gene-identify -> phylogeny
|
|||
|
|
identify_genes = set(results["gene-identify"]["gene_ids"])
|
|||
|
|
phylogeny_tips = set(results["phylogeny"]["tip_labels"])
|
|||
|
|
if identify_genes != phylogeny_tips:
|
|||
|
|
issues.append("Gene IDs mismatch between gene-identify and phylogeny")
|
|||
|
|
|
|||
|
|
# gene-identify -> motif-analysis
|
|||
|
|
motif_genes = set(results["motif-analysis"]["gene_ids"])
|
|||
|
|
if not motif_genes.issubset(identify_genes):
|
|||
|
|
issues.append("Extra genes in motif-analysis results")
|
|||
|
|
|
|||
|
|
# RNA-seq一致性
|
|||
|
|
quant_genes = set(results["rnaseq-quant"]["gene_ids"])
|
|||
|
|
de_genes = set(results["rnaseq-de"]["gene_ids"])
|
|||
|
|
if not de_genes.issubset(quant_genes):
|
|||
|
|
issues.append("DEGs not found in quantification results")
|
|||
|
|
|
|||
|
|
return issues
|
|||
|
|
```
|
|||
|
|
|
|||
|

|
|||
|
|
|
|||
|
|
### 5. 生物学合理性验证 (Biological Plausibility)
|
|||
|
|
|
|||
|
|
**基因家族规模**：
|
|||
|
|
| 基因家族 | 典型规模 | 合理范围 |
|
|||
|
|
|---------|---------|---------|
|
|||
|
|
| SPL | 15-20 | 10-30 |
|
|||
|
|
| WRKY | 50-80 | 40-100 |
|
|||
|
|
| MYB | 100-150 | 80-200 |
|
|||
|
|
| NAC | 100-120 | 80-150 |
|
|||
|
|
|
|||
|
|
**结构域组成**：
|
|||
|
|
- SPL家族应有SBP结构域
|
|||
|
|
- WRKY家族应有WRKY结构域
|
|||
|
|
- 结构域数量与家族特征一致
|
|||
|
|
|
|||
|
|
**进化关系**：
|
|||
|
|
- 同亚家族成员聚类在一起
|
|||
|
|
- 单拷贝基因位置合理
|
|||
|
|
- 无异常长的分支
|
|||

## 特殊场景处理
|
|||
|
|
|
|||
|
|
### 场景1：缺少可选文件
|
|||
|
|
**情况**：structure阶段未生成（用户跳过）
|
|||
|
|
|
|||
|
|
**处理**：不扣分，在报告中标注"用户跳过"
|
|||
|
|
|
|||
|
|
### 场景2：RNA-seq阶段缺失输入
|
|||
|
|
**情况**：用户未提供RNA-seq数据
|
|||
|
|
|
|||
|
|
**处理**：RNA-seq 5个阶段标记为"跳过"，不影响核心阶段评分
|
|||
|
|
|
|||
|
|
### 场景3：进阶阶段未完成
|
|||
|
|
**情况**：kaks、interspecies等未完成
|
|||
|
|
|
|||
|
|
**处理**：根据用户需求判断是否为必需
|
|||
